A friend brought me this computer, it's a gateway NV53 with windows 7.
The problem was that the HDD was locked. Everytime the computer is turned on, the message "Ennter HDD User Password" appears.
For that, we got a new hard drive for it and a windows 7 installation disk. However, with the new HDD now I get the PHE-E61 error. I changed the boot order to the DVD drive with out good results. Even tried with a dvd with ubuntu and even though I hear the dvd spinning, it eventually ends up with the PHE-E61. Have reset BIOS to default values a few times.
I have put the booting from lan option at the very end of the booting order list to no avail.
When I put back the old hard drive and it consistently gives me the "Enter HDD password" message. Then I put back on the new hard drive and again PHE-E61 error.
